[0026] like Figure 2 , Figure 4 , Figure 6 As shown, this utility model provides a forming mold for a bottom cover 40, including a punching mold 10, a first bending mold 20 and a second bending mold 30. The material plate is punched and formed into the bottom cover 40 by the punching mold 10, the first bending mold 20 and the second bending mold 30, thereby realizing the forming of the bottom cover 40.

[0027] like Figure 2-3As shown, the blanking die 10 includes a blanking punch set on the upper die and a blanking groove 101 set on the lower die for blanking out sheet bodies. The blanking punch is a closed loop. The material plate is placed in the blanking groove 101, and the blanking punch is controlled to press the material plate down in the blanking groove 101. The sheet body for forming the bottom cover 40 falls into the blanking groove 101, and a sheet body is formed in one stamping, resulting in high forming efficiency. The blanking die 10 further includes several first punching pins 102 and a first punching insert set on the lower die. The first punching pins 102 punch the middle position of the sheet body in the first punching insert, forming several flip holes on the sheet body.

[0028] like Figure 4-5 As shown, the first bending die 20 includes a first stamping block 201 set on the upper template and three first pad blocks 202 set on the lower template. The first pad blocks 202 form a U-shaped first forming groove. Specifically, one side of the sheet body used to form the surrounding plate 401 is placed in the first forming groove, and the other side is placed on the lower template. The first bending die 20 also includes several second punching inserts set on the upper template and second punching pins 203 set on the lower template. The second punching pins 203 support the other side of the sheet body. When the first stamping block 201 presses down on one side of the sheet body in the first forming groove, the second punching inserts press down on the other side of the sheet body in the second punching pins 203, bending the three edges of one side of the sheet body to form a first bending part 4011, and simultaneously forming several mounting holes on the other side of the sheet body.

[0029] like Figure 6-7 As shown, the second bending die 30 includes a second stamping block 301 set in the upper template and three second pad blocks 302 set in the lower template, the three pad blocks forming a second forming groove. Specifically, the sheet body bent to form three first bent portions 4011 is placed on the second forming groove formed by the second pad blocks 302, and the second stamping block 301 is controlled to press the sheet body into the second forming groove, bending and forming the second bent portions 4021 on both sides of the surrounding plate 401 and the bottom plate 402. Further, the second bending die 30 includes a pressing cylinder set in the upper template, the piston rod of the pressing cylinder is connected to the second stamping block 301, the second stamping block 301 first presses down to initially press the sheet body into the second forming groove, and then the pressing cylinder further presses the second stamping block 301 to make the forming complete.

[0030] In addition, the second stamping opening surface is further provided with a clearance groove. Since the first bending die 20 has already bent and formed three first bending parts 4011 on one side of the sheet body, when the second stamping block 301 presses down to form the surrounding plate 401 and the second bending part 4021, the first bending part 4011 is placed in the clearance groove, which plays a role in clearance.
